The Awakening of RokuThe Awakening of Roku

"Three years after the mess on Lambak Island, Roku has finally mastered airbending and is on track to become the Avatar the world needs. But when he encounters a mysterious illness on his way to Agna Qel'a, he delays his journey and the next phase of his training to prevent the situation from worsening. As Roku ventures deeper into the North and nearer to danger, he soon realizes there's more to the malady than meets the eye. With the assistance of his good friend Gyatso, a gifted Waterbender named Makittuq, and others near and far--including from his past--Roku races to contain the crisis before the disease can ravage the North . . . and beyond."--Amazon.com.
